“They are now considering going to a judge and attempting to get a conservatorship of Amanda. They have previously met with lawyers to discuss the possibility of taking legal control of Amanda’s life. It’s a truly devastating situation for Amanda’s parents and their biggest concern is the health and safety of her.”

It is a mystery how troubled star Amanda Bynes made it from New York to southern California where she allegedly sparked a small fire in a stranger’s driveway before being taken away by cops and put under psychiatric hold.

According to sources wig-loving Amanda was forced to flee the big apple as she couldn’t find anywhere to live and had run out of cash.

Amanda’s journey to Los Angeles has worried pals who told Radar Online the star can’t drive and had no available funds for a taxi.

As Amanda remains under 5150 psych hold after allegedly setting fire to a driveway with a rag and a gas canister more details of her increasingly bizarre behaviour emerge.

It is thought Amanda returned to the Thousand Oaks area as her parents live nearby and some of her cash earned as a child star is protected by them.

Meanwhile eyewitness to the bizarre blaze allegedly caused by Amanda, Andrew Liverpool, told E! Online how he was first on the scene and immediately recognised the star – by her wig.

"I see this girl with her pant leg on fire and a gas can trailing fire through the driveway It looked like her. It sounded like her. She had a wig on," he said.

"I kicked the gas can over and moved it to the middle of the driveway so nothing else would catch on fire.

“She was kind of frantic and discombobulated, and many people rushed over to try to assess the situation and when I looked back up, she was gone."

Liverpool claimed Amanda tried to climb into a cab in her charred jogging bottoms before she was taken away and placed under an involuntary psych hold by police.

It is not thought that Amanda was arrested.

In a recording obtained by TMZ, the caller can be heard saying: "It's a very small fire, it's on a driveway... It's like a small piece of cloth and a gasoline tank which is why I'm calling 911."

Continuing to talk about the petrol tank, the caller added: "I don't know if there's a lot of gasoline in it... No one's injured... It's decently close [to the house], I would say about five feet, and there is a tiny little fire in a crack which is right next to the grass."

Amanda, who was pictured looking disheveled while wearing her infamous blonde wig while shopping in Malibu this week, is reportedly under a 5150 hold - the law used to keep Britney Spears and Mischa Barton on a mental health ward involuntarily for 72 hours in the past.

On Tuesday, Captain Don Aguilar of the Ventura County Sheriff's Office told US website Hollyscoop: "Deputies investigated the incident and determined that she met the criteria of 5150 W&I (California Welfare & Institutions Code). She was detained and taken for a mental health evaluation."

This latest news follows a number of worrying incidents involving the actress - on Sunday the star was reportedly accused of appearing drunk and acting erratically at a retirement community near Thousand Oaks.

Amanda was apparently there to visit a relative but was asked to leave after staff apparently thought she was trespassing, according to TMZ.

She has also been pictured and filmed acting strangely while out and about in New York and recently attended a court hearing after she allegedly tossed a marijuana bong from the window of her 36th floor apartment.
